Section 3 describes the computerized maintenance management system software used by UWS-MS, and the associated equipment, parts, and materials tracking procedures. Section 4 describes new standard operating procedures developed for maintenance of the storm cells (equalization basins) at the Savanna Street WWTP to avoid excess sludge accumulation, and for maintaining proper sludge inventories within the main treatment plant unit processes. The WWTP Preventative Maintenance program is described in Section 5, including standard operating procedures and a summary of the qualifications and training requirements for O&M staff. Implementation of the program is discussed in Section 6. 3 City of Jackson WWTP Operations and Maintenance Program 4 City of Jackson WWTP Operations and Maintenance Program 2.0 Jackson Wastewater Treatment Plants The City of Jackson operates three wastewater treatment plants (WWTPs). A brief description of each facility is provided below. 2.1 Savanna Street WWTP The Savanna Street WWTP serves most of the population in the City together with flow from three satellite utility authorities. These contribute wastewater flow from western Rankin County, southern Madison County, and the Pearl River Valley Water Supply District (Barnett Reservoir area). The Savanna Street plant has a permitted capacity of 46 MGD summer and 60 MGD winter. Annual flows to the plant currently average about 45 MGD. The Savanna Street WWTP is a conventional activated sludge facility without primary clarifiers. Flow is received through the 50-ft deep 96-in diameter West Bank interceptor. The West Rankin force main also discharges to the West Bank interceptor upstream of the influent pump station. Major unit processes are: Influent trash racks. Influent pump station. Headworks with two mechanically cleaned bar screens, two screenings compactors, two vortex grit removal units, two grit pumps, and two grit washing units. Bioselector basin to promote good sludge settling. Ten aeration basins with fine bubble tube diffusers, each 2.56 MG in volume. Aeration blower facility with four single stage blowers. Five 140-ft diameter secondary clarifiers. Two return sludge pump stations. Two waste activated sludge pumps. Chlorine storage and feeding equipment for disinfection. Chlorine contact channel. Sulfur dioxide storage and feeding equipment for dechlorination. Effluent pump station for use when river levels are high. Outfall to the Pearl River. Three excess flow equalization basins. Two aerobic digesters. Two gravity sludge thickeners. Thickened sludge holding tank. Three two meter width belt filter presses for sludge dewatering. A schematic of the Savanna Street WWTP is shown in Figure 2-1. An aerial view of the plant is shown on Figure 2-2. 5 City of Jackson WWTP Operations and Maintenance Program Figure 2-1 Savanna Street WWTP Schematic Figure 2-2 Savanna Street WWTP Aerial View 6 City of Jackson WWTP Operations and Maintenance Program 2.2 Presidential Hills WWTP The 0.75 MGD Presidential Hills WWTP was constructed as a conventional aerated lagoon system followed by effluent filtration and chlorine disinfection. A new sequencing batch reactor (SBR) treatment plant is nearing completion of construction and will startup in mid2014. When the new plant is on-line the aerated lagoons will be used as flow equalization basins. The SBR was constructed in response to new, more stringent permit limits for nutrients. A process schematic of the new plant is shown on Figure 2-3. Figure 2-3 Presidential Hills WWTP Schematic 2.3 Trahon/Big Creek WWTP The 4 MGD Trahon/Big Creek WWTP uses the oxidation ditch process. Principal unit processes are: Influent pump station Mechanical bar screens Aerated grit chamber with grease removal Two Carousel® oxidation ditches Two secondary clarifiers Chlorine contact basin Aerobic digestion The plant does not have any on-site mechanical sludge thickening or dewatering capability. An aerial photo of the plant is shown on Figure 2-4. 7 City of Jackson WWTP Operations and Maintenance Program Figure 2-4 Trahon/Big Creek WWTP 2.4 WWTP Contract Operations The City of Jackson has contracted operation and maintenance of the wastewater treatment plants and all pump stations to United Water Services Mississippi LLC (UWS-MS). The company is a subsidiary of the global private O&M conglomerate, Suez Environnement. United Water has 2,350 employees in the U.S., operates 90 municipal systems, and is one of the largest private O&M companies. UWS-MS has 42 full time staff in Jackson to operate the City’s wastewater treatment plants and pump stations. 8 City of Jackson WWTP Operations and Maintenance Program 3.0 Equipment, Parts and Material Inventory A characteristic of a quality WWTP O&M program is a good system of managing the inventory of operating equipment, spare parts, and materials. A description of the inventory control system used by the City, through its professional contract operator UWS-MS, is described in this Section. 3.1 UWS-MS Operational Support Systems United Water O&M staff employs several resources to manage inventories required in WWTP operations. These resources are briefly described below. Table 3-1 defines some of the key elements and terminology used by UWS-MS in operating and maintaining the plants. Oracle Enterprise Performance Management UWS-MS uses an Oracle Enterprise Performance Management (EPS) system to provide integrated planning, analysis, accounting, and reporting tools to aid O&M staff in proper operation and management of their assigned facilities and systems. The Oracle EPS has computer modules that can assist with: Planning Budgeting Performance monitoring Progress tracking Communications management Scheduling and forecasting Cost management Reporting The EPS is used in operation and management of all facilities assigned to UWS-MS, including the wastewater treatment plants. eRPortal Asset and Maintenance Management System UWS-MS has adopted a standardized computerized maintenance management system (CMMS) at the facilities they operate. This system is developed around the eRPortal CMMS software platform, which has been fully implemented by UWS-MS in Jackson. The eRPortal software provides enterprise asset management and materials management applications designed to optimize operations, maintain assets and infrastructure, and manage all related materials, resources, and logistics. The software is user friendly and is easily configurable to each individual facility. eRPortal CMMS effectively manages both planned and unplanned work order logistics. The system is designed for operational flexibility and can be adapted to specific work environments and workflows. eRPortal also supports GASB34 accounting standards and EPA CMOM regulations with “cradle-to-grave” asset tracking capabilities and environmental protection compliance. These capabilities include tracking warranties and 9 City of Jackson WWTP Operations and Maintenance Program Table 3-1 United Water Services Mississippi LLC Savanna Street WWTP OPERATIONS & MAINTENANCE GLOSSARY ACRONYM / ABBREVIATION DESCRIPTION A document, which is an output from a meeting, that defines the action items that needs to be accomplished, who is responsible, and when it will be completed.

The system is specifically designed to simplify maintenance and compliance tasks for water and wastewater treatment plants. Operations Data Management UWS-MS collects data from a variety of sources that is used to monitor and plan facility operations. These include instrumentation readouts delivered through SCADA, manually recorded data points collected by operators as part of daily operations, and analytical data generated by on-site and off-site laboratories. The operations data is managed locally using a custom designed Excel-based spreadsheet system. 3.2 Inventory Control UWS-MS maintains a detailed inventory control system with the capability to track usage and determine replenishment needs. Complete inventories are kept of spare parts, materials, equipment, and some consumables. An example of the UWS-MS inventory master list is shown on Table 3-2. Spare parts are managed using the eRPortal CMMS. Figure 3-1 and Figure 3-2 illustrate the inventoried parts, parts classification, and spare parts tracking reports maintained on eRPortal. Separate records are kept of spare parts inventory quantity changes and maintenance activities performed, as shown on the Item Transaction Log Report (Table 3-3). Inventory change adjustments are tracked in more detail as shown on Table 3-4. Some of the inventory records kept are redundant and carry over from before eRPortal was implemented in 2011. Through these multiple inventory tracking methods, UWS-MS has a continuous accurate picture of the state of the current spare parts, materials, and equipment inventory. eRPortal is also used to generate automated item reordering requests when the quantity of the inventoried item falls below the “Must Have” quantity. An example of the item reordering screen from eRPortal is shown on Figure 3-3. A purchase order requisition is subsequently generated to replenish the item. 3.3 Vendor Services UWS-MS maintains an up-to-date list of vendors and suppliers able to furnish all spare parts, materials, and equipment required by the plant. Complete records are kept on all vendors whose products and services are required to operate and maintain the plants. Having access to and good relations with a wide variety of outside vendors is an operational 11 City of Jackson WWTP Operations and Maintenance Program necessity. Detailed vendor contact information is maintained on a master list as shown on Table 3-5. An excerpt from the Oracle Enterprise Performance Management system illustrating some of the vendor data recorded is shown on Figure 3-4. The UWS-MS vendor list is extensive, and as a result a wide variety of suppliers, repair service companies, and other businesses are available to provide any needed good or service required by the plants. 3.4 Management of Critical Spare Parts A key concept in a strategic asset management program is the criticality of assets. Consequently, UWS-MS has a defined procedure for identification and tracking of critical plant components and equipment. The list of critical equipment is developed through analysis of probability and consequences of failure. This list is maintained and utilized by UWS-MS to effectively sustain the project assets. Failure of critical equipment may result in a potential: Unsafe or hazardous work environment Environmental excursion or violation Contract compliance – Quality Contract compliance – Throughput Major cost impact Client community nuisance Six different criticality ratings are used to prioritize WWTP components and potential failures that would have the greatest impact on treatment capability. These ratings are: CRITICAL/Emergency – Highest priority; break schedule for immediate repair CRITICAL/High Importance –Higher priority; break schedule for immediate repair CRITICAL/Significant – Higher priority; break schedule for immediate repair NONCRITICAL/Concern – Priority; begin repair work within 24 hours NONCRITICAL/Minor Impact – Lower priority; schedule to repair within a week NONCRITICAL/No impact – Lowest priority; schedule repair in next weekly commitment meeting 12 City of Jackson WWTP Operations and Maintenance Program Each critical item is assigned an Importance Ranking and a Priority Ranking as shown on Table 3-6. For each critical component, the importance ranking is determined by considering potential impacts to safety, environment, quality, wastewater throughput, operations costs, and degree of nuisance. An excerpt from the critical equipment list for the Trahon-Big Creek WWTP showing the priority and ranking for each is given on Table 3-7. The status of critical equipment requiring maintenance action is tracked daily. An example of the Daily Critical Equipment Status Report is shown on Table 3-8. This report is used to insure that critical spare parts and materials are stored and maintained in inventory at the WWTP. In summary, UWS-MS maintains a capable and efficient inventory management system. No changes appear to be required to the current inventory tracking system for equipment, materials, or critical spare parts. 13 Table 3-2 Jackson Wastewater Treatment Plants Master Spare Parts and Equipment List City of Jackson WWTP Operations and Maintenance Program 14 City of Jackson WWTP Operations and Maintenance Program Figure 3-1 eRPortal CMMS Spare Parts Tracking Figure 3-2 eRPortal CMMS Inventory Reports 15 City of Jackson WWTP Operations and Maintenance Program Table 3-3 United Water Services Mississippi LLC Savanna Street WWTP Item Transaction Log Report Report Filters: Active Items Only Item Number Date/Time User ID Order # Description Qty On Hand 000003 UW 105 Oil Change 2/1/2013 4:14:52 PM erussell Create New Item 2/1/2013 4:14:52 PM 2/1/2013 4:14:53 PM Add Location Maint erussell 2/1/2013 4:17:36 PM Item Restock Change 200309-1-1 New Issue Line 0.00 1.00 1.00 0.00 -1.00 1.00 000004 M&O Door Install 2/4/2013 2:26:36 PM erussell Create New Item 2/4/2013 2:26:37 PM 2/4/2013 2:26:37 PM erussell 2/4/2013 2:28:47 PM 0.00 Add Location Maint 1.00 Item Restock Change 0.00 200310-1-1 New Issue Line -1.00 1.00 1.00 BELT0022 Bottom Belt 2.2x16.3 2/1/2013 3:53:57 PM erussell Create New Item 2/1/2013 3:53:58 PM 2/1/2013 3:53:58 PM erussell 2/1/2013 4:05:56 PM 0.00 Add Location Maint 1.00 Item Restock Change 0.00 200308-1-1 New Issue Line -1.00 1.00 0.00 BELT0023 Top Belt 2.0x15.7 2/1/2013 3:55:53 PM erussell Create New Item 2/1/2013 3:55:53 PM 2/1/2013 3:55:54 PM erussell 0.00 Add Location Maint 1.00 Item Restock Change 0.00 1.00 PARTS0006 1 1/2" BALL VALVE - 1 1?2" PVC BALL VALVE 11/2/2012 9:24:04 AM system Change Product Class 0.00 11.00 PARTS1002 Vacuum Truck Cylinder Repair 11/29/2012 2:04:45 PM erussell Create New Item 11/29/2012 2:04:45 PM 0.00 Add Location Maint. 1.00 1.00 11/29/2012 2:04:45 PM erussell Item Restock Change 0.00 11/29/2012 2:05:01 PM erussell Change 0.00 1.00 -1.00 0.00 11/29/2012 2:06:33 PM 200301-1-1 New Issue Line PARTS1003 Incline Conveyor Roller Repair 12/4/2012 10:38:48 AM erussell 12/4/2012 10:38:49 AM 12/4/2012 10:38:49 AM erussell 12/4/2012 10:54:42 AM Create New Item 0.00 Add Location Maint. 1.00 Item Restock Change 0.00 200302-1-1 New Issue Line -1.00 1.00 0.00 PARTS1004 Incline drive roller repair 12/4/2012 11:01:43 AM erussell Create New Item 0.00 16 City of Jackson WWTP Operations and Maintenance Program Table 3-4 United Water Services Mississippi LLC Savanna Street WWTP Inventory Adjustment Report Cost Adjustment ItemNumber / Description Date OldQty New Qty UM AF0007 7/8/10 9.00 AF0010 7/8/10 BELT0002 9/7/11 0.00 14.00 9.00 0.00 14.00 Change(+) EA EA EA Change(-) OldCost 0.5900 3.5600 6.7100 NewCost UM 1.5000 EA 0.00 8.19 4.9500 EA 0.00 0.00 7.2500 EA 0.00 7.56 27.5000 EA 0.00 10.00 4.1500 EA 0.00 0.00 58.0000 EA 0.00 0.00 58.0000 EA 0.00 0.00 3.7500 EA 0.00 0.00 49.0000 EA 0.00 0.00 7.5000 EA 0.00 0.00 1.5000 EA 0.00 129.00 14.5000 EA 0.00 0.00 1.0000 EA 0.00 0.00 0.5000 EA 0.00 0.00 4.5900 EA 0.00 0.00 54 inch drive belt for the effluent blowers BELT0003 9/7/11 4.00 4.00 EA 25.0000 Cedar Creek Netzsch Pumps BELT0004 9/9/11 0.00 0.00 EA 3.8000 ICPS second Floor Vent Fan BELT0007 BELT0007 BELT0016 BELT0034 BELT0042 BOLT0002 BOLT0003 BOLT0004 BOLT0010 BRNG0003 3/26/09 3/26/09 4/28/10 8/20/08 8/20/08 0.00 0.00 0.00 0.00 0.00 10/22/09 86.00 7/8/10 1/21/10 10/2/08 10/1/08 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 86.00 0.00 0.00 0.00 0.00 EA EA EA EA EA EA EA EA EA EA 5.8000 5.8000 4.3600 48.0000 7.0000 0.0000 0.0000 0.0000 0.0000 0.0000 17 City of Jackson WWTP Operations and Maintenance Program Figure 3-3 eRPortal Inventory Item Reordering Screen 18 City of Jackson WWTP Operations and Maintenance Program Table 3-5 United Water Services Mississippi LLC Savanna Street WWTP Vendor Master List Updated: 6/7/2013 Name/Alias ID Contact AAA Cooper AAACOOPE Clayton Aamco Transmission Address Phone/Fax/EMail Status 124 Interstate Drive Richland 601-936-9600 Active AAMCOTRA Kelty 943 South State Street Jackso 601-948-7343 Active Ace Bolt & Screw ACEBOLTS Mike PO Box 22533 Jackson, MS 3922 601-355-3448 Active Acme Products ACME Doug Ansuini 59 Interstate Drive 413-739-7390 Active Suite 30 413-739-0299 West Springfield, MA 01089 dansuini@appliedst.com Advance Auto Parts ADVANCEA Robert 3318 Terry Road Jackson, MS 3 601-373-5185 Active Agri Dyne AGRIDYNE Harvey PO Box 458 Bolton, MS 39041 601-866-2233 Active Air Contractors AIRCONTR Donna PO Box 6843 Jackson, MS 39282 601-373-9296 Active Applied Industrial Technologie AIT Dave Brody 2029 Wyandotte 421-0407 Active PO Box 412756 283-3287 KCMO, MO 64141 Allis Chalmers ALLISCHA American Carbon Industries AMERICAN Jackson, MS PO Box 11236 Birmingham, Al 3 601-922-8725 Active 205-251-4000 Active 205-252-6300 Applewhite Equipment & Supply APPLEWHI Lloyd Highway 49 South Florence, MS 601-845-1964 Active Applied Industrial APPLIEDI Jeff 531 Highway 49 South Richland 601-939-1417 Active Aqua Aerobics Systems AQUAAERO 6306 N.

Jackson WWTP Operations and Maintenance Program 4.0 Solids Management United Water has in place procedures for storage, handling, and processing of sludge from the three wastewater treatment plants. The solids management procedures, schedules, and standard practices are described in this section. 4.1 Sludge Sources Each of the WWTPs produces sludge that must be properly managed. The sludge streams consist of: Presidential Hills WWTP – A new 0.75 MGD mechanical treatment plant using the sequencing batch reactor process is starting up in mid-2014. Waste activated sludge generated by the SBR will be conveyed to the Savanna WWTP for processing. Trahon/Big Creek WWTP – The existing 4 MGD oxidation ditch plant produces waste activated sludge which is trucked in liquid form to the Savanna WWTP for processing. Current flows to the plant average about 2 MGD. About 6,500-gal, or one truck load, of WAS is hauled to the Savanna plant daily. Savanna WWTP – Sludge is generated at the Savanna plant from two main sources: 1. Waste activated sludge – Currently averaging about 900,000 gal/day of 1.4% secondary sludge for an average plant flow of about 45 MGD. This plant does not have primary clarifiers. 2. Storm cell storage – Any excess wet weather flow diverted to the storm cell flow equalization basins for temporary storage contains some solids. Over time these solids will accumulate in the storm cells and will require removal. A project to remove sludge from the Savanna WWTP storm cells was completed in April 2014. As noted above, all wastewater sludge generated in the City of Jackson and contributing satellite communities is centrally handled at the Savanna WWTP. 4.2 Waste Activated Sludge The Savanna WWTP is a conventional activated sludge plant without primary clarifiers. A portion of the waste activated sludge must be removed from the process daily. The WAS is sent to aerobic digesters to allow some solids reduction through destruction of a portion of the volatile solids. In the digesters, the sludge is further thickened by intermittent cycles of settling and decanting of supernatant. From the digesters, the sludge flows to two gravity sludge thickeners to provide additional solids concentration. Thickened WAS is then pumped to a sludge holding tank. Feed pumps transfer the thickened sludge to belt filter presses and a centrifuge where polymer is added and the sludge is dewatered. After 25 City of Jackson WWTP Operations and Maintenance Program dewatering, the sludge is hauled to various disposal sites, spread on agricultural land, and then incorporated in the subsoil. A copy of the current Savanna Street WWTP Sludge Management Plan prepared by UWS-MS is provided in Appendix A. A schematic of the sludge processing operation is shown on Figure 4-1. Currently, the plant owns three 2-meter width belt presses and leases one additional belt press and a centrifuge. As described in the Savanna Street Wastewater Treatment Plant Comprehensive Performance Evaluation Report (May 31, 2014), the original belt presses are at the end of their useful life and require replacement. A major upgrade to the plant’s dewatering capability will be performed as part of other plant improvement needs described in the CPE report. Currently, the dewatering equipment is operated seven days/week, often 24 hours/day. There are three dedicated dewatering operators responsible for operating and maintaining the equipment. These operators are assisted by the shift operators after hours and as needed. Management is provided by a full-time Dewatering/Land Application Supervisor. Dewatered sludge hauling and land application services are provided by a private contractor. UWS-MS has developed Standard Operating Procedures (SOPs) for the dewatering operation. The Belt Press Dewatering SOP and the Centrifuge Dewatering SOP are provided in Appendix B. Figure 4-1 Savanna Street WWTP Solids Handling Schematic 26 City of Jackson WWTP Operations and Maintenance Program 4.3 Storm Cell Sludge During periods of high wastewater flows, excessive flow beyond the main plant treatment capacity is diverted to the storm cell flow equalization basins. These three cells have a combined storage capacity of 171 MG. A 100 MGD storm water pump in the influent pump station is used to divert the flow. Additionally, a second diversion point to the storm cells can be used for flows from the Rankin County force main. After peak flows recede, a return line from Cell 3 is used to return stored flow to the West Bank Interceptor for treatment by the plant. Arrangement of the three storm cells is shown on Figure 4-1. Figure 4-2 Savanna Street WWTP Storm Cells UWS-MS has developed a new SOP for management of wet weather flows and the storm cell diversion process. The Savanna Street WWTP Wet Weather Operating Plan is included in Appendix B. A project to remove accumulated sludge from the storm cells was completed in April 2014. Following successive diversions of future excess wet weather flows, sludge will again slowly accumulate in the storm cells over time. In the future, sludge levels will be monitored and measured on an annual basis. Accumulated sludge will be removed from the storm cells as needed, estimated at approximately every 5 years. Sludge removed from the storm cells will 27 City of Jackson WWTP Operations and Maintenance Program be disposed of off-site by land application or landfilling, depending on the sludge characteristics. 28 City of Jackson WWTP Operations and Maintenance Program 5.0 Preventative Maintenance Program United Water has an active a Preventative Maintenance Program in force for the wastewater treatment plants and pump stations operated and maintained for the City of Jackson. The purpose of the PM program is to provide proactive preventative and predictive maintenance to minimize required corrective maintenance. The UWS-MS Preventative Maintenance Program is described in this section. 5.1 UWS-MS Preventative Maintenance Program The City of Jackson has contracted operation and maintenance of the wastewater treatment plants and all pump stations to United Water Services Mississippi. The City still provides maintenance services for the gravity sewers, but essentially all mechanical and electrical equipment maintenance in the system is the responsibility of UWS-MS. As one of the largest private O&M companies, UWS-MS has adopted a standardized computerized maintenance management system (CMMS) at the facilities they operate. This system is developed around the eRPortal CMMS software platform, which has been fully implemented by UWS-MS in Jackson. The eRPortal CMMS incorporates the following features. A powerful preventative maintenance (PM) scheduling module with the flexibility to control when work orders should be triggered. For triggered PM’s, the work order includes procedures, parts, personnel assignments, skill/labor-code requirements, and other required data. Information displayed on the work order is only what is actually needed to complete the assignment. A work-order management module that allows tracking of time, materials, schedules, dates, and responsiveness. A supervisory control and data acquisition (SCADA) interface that permits operators to view upcoming and open work orders and full details of work-order history without leaving their operating consoles. They also can quickly enter work-order requests that send out e-mail notifications. 29 City of Jackson WWTP Operations and Maintenance Program The SCADA interface also allows run time-based preventive maintenance work-order triggers. The interface can also generate condition- and predictive-based orders that incorporate any combination of sensors (vibration, temperature, or pressure) or equipment usage being monitored. Parts tracking and management functionality that identifies, allocates, and tracks replacement parts required for repetitive tasks. Preferred vendors, blanket purchase orders, and procurement contracts can be managed from within the system. Extensive item properties can be tracked, including multiple cost methodologies, serialization/lot numbers, weight, description, type, class, and dimension. The system can utilize existing barcode IDs or create new ones on-demand or at time of purchase order receipt. Web browser-enabled architecture with complete supply chain connectivity. This allows the software to interface via the Web or other connectivity formats with all internal and external systems at key touch points where information exchange is critical. The following sections provide documentation how the UWS-MS maintenance staff and the eRPortal CMMS facilitate completion of required PM activities. A screenshot of the eRPortal CMMS home screen is shown on Figure 5-1. 5.2 O&M Staffing and Resource Commitments O&M Staff Organization UWS-MS has a single maintenance department responsible for maintaining the City’s three wastewater treatment plants and all of the pump stations.

O&M Staff Training All UWS-MS O&M staff receives initial (upon hire) and periodic refresher training on a variety of activities, knowledge, and skills required for them to perform their jobs successfully and safely. An excerpt of the UWS-MS operations staff training requirements is shown on Figure 5-6. An example of maintenance staff training requirements is shown on Figure 5-7. 36 Figure 5-6 Operations Staff Training Requirements City of Jackson WWTP Operations and Maintenance Program 37 City of Jackson WWTP Operations and Maintenance Program 38 City of Jackson WWTP Operations and Maintenance Program 5.3 WWTP PM Program This section describes the preventative maintenance programs for treatment plant systems and equipment. The PM program consists of periodic inspection of all equipment containing electrical, mechanical, and physical components. Guidance to Managers and Field Personnel UWS-MS provides appropriate guidance to managers and field personnel for scheduling and performing preventative maintenance activities on wastewater treatment plant equipment. This guidance includes detailed PM tracking using the eRPortal CMMS to insure that all scheduled PM activities are routinely completed. The guidance consists of: Identification of all systems and equipment where PM is required. Identification of critical equipment required to maintain treatment operations. Itemization of required PM tasks for each item of equipment. Instruction in equipment, tools, and materials required to complete PM work. Training necessary to complete PM activities. Instruction on documentation to update the eRPortal CMMS used to track PM history. Preventative Maintenance Practices Preventative Maintenance is performed on all plant equipment where it is identified as being required, either critical or non-critical. Procedures for identification and tracking of critical equipment were described in Section 3. UWS-MS maintains a library of equipment O&M Manuals furnished by the various manufacturers of the equipment. The manufacturer’s O&M instructions are followed in scheduling and performing maintenance tasks, including preventative maintenance. Maintenance staff are instructed in the skills, tools, and procedures necessary to perform the preventative maintenance activities. The training also covers procedures for recognizing various indicators that the equipment is experiencing other problems, and that corrective maintenance is required. Preventative Maintenance Scheduling Preventative maintenance activities are scheduled in the eRPortal CMMS as defined by the UWS-MS Maintenance Manager and Maintenance Planner. An example PM schedule is shown on Figure 5-8. Preventative Maintenance Work Orders All maintenance work orders are generated and tracked using the eRPortal CMMS. A screen shot of the eRPortal maintenance home screen is shown on Figure 5-9. Instructions to staff on how to create and close a work order are listed on Table 5-1. 39 City of Jackson WWTP Operations and Maintenance Program Figure 5-8 Example PM Schedule Preventative Maintenance Summary by Asset Report Filters: DivisionID = LS PM# Frequency Est Hours DueDat Craft e Asset: LS01-AMANDA-LANE - LIFT STATION WOType PMNotes Department: LS01 - Amanda Lane 2069 365 Days 2.00 12/28/2013 M - Maintenance 2 - PM Lift Station Pump Inspection - Annual 2086 30 Days 0.20 07/03/2013 M - Maintenance 2 - PM Lift Station Inspection (South) - Monthly 2 - PM Thermography Inspection Lift Stations- Annual 2.20 Asset Total: Asset: LS01-CNTR-PANEL - CONTROL PANEL 2080 Asset Total: 365 Days Department: LS01 - Amanda Lane 1.00 02/01/2014 M - Maintenance 1.00 eRPortal CMMS PM Scheduler 40 City of Jackson WWTP Operations and Maintenance Program Figure 5-9 Jackson eRPortal Computerized Maintenance Management System Work Order Generation and Tracking 41 City of Jackson WWTP Operations and Maintenance Program 42 City of Jackson WWTP Operations and Maintenance Program 5.4 Predictive Maintenance In addition to normal PM, UWS-MS also proactively performs certain Predictive Maintenance activities. Predictive Maintenance is a process used to identify degree of wear and useful life remaining of equipment components and parts that otherwise show no outward sign of failure. An example is the annual thermographic inspection of control panels and motors as shown on Figure 5-10. Thermographic inspection involves infrared scanning of electrical control panels and motors, as well as other components such as equipment bearings, to detect heat buildup. If a hot spot is identified and determined to be excessive, more detailed investigation will be performed and required corrective maintenance will be scheduled. 5.5 Corrective Maintenance A good preventative maintenance program will minimize equipment malfunctions that result in the need for unscheduled repairs, referred to as corrective maintenance1. While UWS-MS has aggressive Preventative Maintenance and Predictive Maintenance programs in place, corrective maintenance actions are periodically required to perform needed repairs on equipment and systems. Procedures used by the City of Jackson to perform corrective maintenance, when it is needed, are described below. Repair or Replace Decision For each major item of equipment requiring repair, a decision is first made whether to perform the repair or replace the item with new equipment. UWS-MS has developed a standard procedure that is used in evaluating whether to repair or replace the equipment. The UWS-MS decision criteria used are: 1 Utilize eRPortal CMMS to review equipment maintenance history. Consider age, number of failures, maintenance labor hours expended, and past costs associated with equipment repairs. Consider availability and lead time for replacement parts. If size is less than 5 HP, the motor should be replaced. If above guidelines suggest that repair may be a good option then request quotes for repair as well as replacement. If repair cost is more than 50% of the replacement cost, estimate the years of useful life for the repair and replace options. Determine the annual cost for each option using the available quotes and select the lowest annual cost option. If repair cost is less than 50% of the replacement cost, proceed with repair. ‘Reactive maintenance’ is the term used in the Consent Decree. 43 City of Jackson WWTP Operations and Maintenance Program Figure 5-10 Predictive Maintenance Example Thermographic Inspection of Electrical Components Control Panel Thermography Inspection Results 44 City of Jackson WWTP Operations and Maintenance Program Work Order Procedures When corrective maintenance needs are identified, a Work Order is entered into the eRPortal CMMS by the O&M staff. Execution of the Work Order then follows the procedure outlined on Figure 5-11. Scheduling and tracking of Corrective Maintenance Work Orders is performed through the UWS-MS eRPortal CMMS as described above. Figure 5-11 Corrective Maintenance Work Flow For all Work Orders, whether they be preventative, predictive, or corrective, Purchase Orders to UWS-MS registered vendors for outside repair services required, parts not in inventory, or other outside purchases needed to complete the corrective maintenance actions are generated using eRPortal CMMS as described in Section 3. Maintenance Tracking System Wastewater treatment plant equipment inspection and maintenance activities are documented using the eRPortal CMMS work order system as described in Section 3. The CMMS is used for maintenance tracking and record keeping. As equipment maintenance activities are completed by the O&M crews, the results are entered into eRPortal and a work order completion log is generated. Statistics are also kept on work order history. Work order completion status reports are generated by the O&M staff using the UWS-MS eRPortal CMMS as needed. The reports can be easily produced using any date range required, such as prior year, year-to-date, monthly, or any other parameters, depending on the purpose of the report. Maintenance reports are generated as directed by the Plant Manager, Maintenance Manager, or other O&M staff member as requested or necessary.

These procedures were developed to limit the downtime of the equipment or facility during the abnormal conditions. Examples are the Wastewater Treatment Plant Power Failure SOP and the Control Panel Damage SOP included in Appendix B. 5.7 Operation and Maintenance Program Summary The City of Jackson currently has in place a sophisticated maintenance program for its wastewater treatment plants implemented by its professional contract operator, UWS-MS. A state of the art computerized maintenance management system, eRPortal, is used to schedule maintenance activities, generate work orders, and track maintenance completed. UWS-MS has a fully qualified and trained staff assigned to perform maintenance functions. Including the WWTP O&M standard operating procedures described in this report, the current City of Jackson WWTP O&M program is compliant with the requirements listed in the Consent Decree. Consequently, no further implementation measures or additional changes to the current program appear to be necessary. 47 Appendix A Savanna Street WWTP Sludge Management Plan City of Jackson, Mississippi Sludge Management Plan Introduction The City of Jackson Savanna Street WWTP is a 46.0 MGD activated sludge plant with storm water holding lagoons. The plant stabilizes waste activated sludge by means of aerobic digestion. The digestion process produces thickened, liquid, stabilized organic bio-solids at a concentration of about 2% and dewatered of about 20%. The bio-solids meet the requirements established by Mississippi Department of Environmental Quality (MDEQ) and the US EPA for Land Application. Sludge from the City’s Trahon/Big Creek WWTP and Presidential Hills WWTP is hauled to the Savanna Street plant for processing. The Trahon/Big Creek WWTP is a 4.5 MGD oxidation ditch activated sludge plant. The wasted sludge from this facility is thickened in an aerobic digester prior to hauling. The Presidential Hills WWTP is a 0.75 MGD aerated lagoon activated sludge plant. It is being replaced by a sequencing batch reactor activated sludge plant that will start up in mid-2014. Sludge from the new plant will be conveyed to the Savanna Street plant. The sludge de-watering operation utilizes the following basins and equipment to achieve Class B sludge: gravity thickener, two aerobic digesters, 3-2 meter belt filter presses (avg. 70 gals/min sludge feed rate), 1 centrifuge (avg. 250 gals/min sludge feed rate), and 1-2.2 meter belt filter press (avg. 450 gals/min sludge feed rate). Liquid polymer is used on all dewatering machines to achieve coagulation. The selected method of sludge disposal is by surface land application at agronomic rates. All application sites are permitted for sludge application and all but one are privately owned by local farmers. The Management Plan is found below. This will include loading rates based on expected sludge quality and quantity, the crop selected by the land owner and limiting constituent for application. The anticipated limiting constituent is nitrogen. The plan will also include the application method, harvest requirements, monitoring, pollutant tracking and monitoring. When land application is not possible due to wet weather conditions, etc., de-watered sludge will be disposed of at the local landfill currently being operated by BFI. The management plan is in compliance with the State and Federal reporting guidelines pertinent to 40 CFR 503 regulations, as well as on the findings of specific investigations, historical operational data and input from various United Water associates experienced in the land application of bio-solids. The management plan is applicable of bio-solids and those that are to be permitted in the future. A-1 Management Plan The dewatered sludge outlined in this program shall follow these buffer zone requirements: Property Line Waters of the Wells, Exterior Dwellings State Public/Private Roadways De-watered 200 ft. 200 ft. 500/250ft. 200 ft. 300 ft. All soil pH levels will be monitored and adjusted accordingly by applying Lime Dewatered application of bio-solids will be applied to slopes of 6 to 12%. Bio-solids will be applied according to agronomic loading rates for each crop it is applied upon. Bio-solids will not be applied to flooded, frozen, or snow covered ground. Bio-solids will not be applied to land that adversely affect threatened or endangered species. No annual pollutant loading rate shall be exceeded. Signs will be posted that restrict access to the application sites. Bio-solids will not be stockpiled at the site unless in an enclosed tank or building for a period not to exceed 30 days. No grazing shall be allowed on the site for 30 days after bio-solids application. Public access to the site shall be restricted for 30 days when there is low potential for public exposure and one year when there is high potential for public exposure. Application Sites This program currently includes 12 sites. They are labeled as follows: Byram Landfill Permitted for 560 acres Kainz Property Permitted for 137.3 acres Varnado Property Permitted for 34.7 acres Mason Property Permitted for 75.1 acres Murphy Davis Property Permitted for 298.8 acres Holmes Property Permitted for 261.8 acres Fisher Property (Site #1) Permitted for 150 acres Fisher Property (Site #2) Permitted for 109 acres Berry Property Permitted for 223.8 acres Darden Property (Site #1) Permitted for 624 acres Darden Property (Site #2) Permitted for 32 acres Sullivan Property Permitted for 208.4 acres A-2 Sludge Quality The main constituents of concern are nitrogen (including ammonia, total kjeldahl nitrogen, nitrates, and nitrites). Values for nitrogen were obtained from the previous years. Below are the sludge metal results annualized for the 2012 calendar year. All of the laboratory results below can be found on the laboratory’s letterhead and the specific analytical method (also contained in annual 40 CFR 503 Report) Dewatered Sludge Metals Arsenic Cadmium Chromium Copper Lead Mercury Molybdenum Nickel Selenium Zinc Ceiling Limits mg/kg 75 85 3000 4300 840 57 75 420 100 7500 2012 Results 9.65 1.1 18.4 186 17.4 0.4 9.7 18.1 15.1 290.8 A-3 Sludge Loading Rates Nutrient Uptake Rate for Crops lbs. / acre – year (table 4-11, EPA Process Design Manual – Land Treatment of Municipal Wastewater) Nitrogen Phosphorus Potassium Forage crops: Coastal Bermuda grass Ryegrass Tall fescue 356 – 600 31 – 40 201 178 – 250 134 - 290 54 – 76 27 241 – 290 268 18 - 27 13 9 – 18 13 98 36 27 – 49 18 - 40 Field crops: Corn 156 – 178 Cotton 67 – 98 Soybeans* 222 Wheat 143 * Legumes will also take nitrogen from the atmosphere. Land application will be based on the EPA schedule 40 503 regulations that state the agronomic loading rate of plant available nitrogen for the selected crop will be met. The table below, current permitted fields, are planted in Coastal Bermuda grass. Bermuda grass has an uptake rate of 300 to 600 lbs. of plant available nitrogen per acre per year. The average total nitrogen is 7.8 percent of the organic sludge. We have selected 400 lbs. per acre as our maximum loading rate. Crop harvest will remove the nitrogen from the fields. Nitrogen will be mineralized over a 10 year period as regulated by the bio-solids requirements found in 391-3-6-.17. Ultimately, 56% of the total kjeldahl nitrogen is plant available over the 10 year period. The nitrates, nitrites, and ammonia are immediately plant available in the first year. The only part that would not be plant available would be lost through de-nitrification and volatilization. The following table lists the percentage of mineralization: Year 1 Year 2 Year 3 Year 4 Year 5 Year 6 Year 7 Year 8 Year 9 Year 10 Mineralization Table for bio-solids 30% 15% 8% 4% 3% 3% 3% 3% 3% 3% We will use HACH WIMS and MS Excel to track and mineralize the nitrogen and all other constituents applied, including dry tons per acre. The programs are set up to track nitrogen for any crop that is planted and the corresponding nitrogen needs for that crop. They will also track all priority pollutants and forecasts the longevity of the sites. A-4 Land Application Operations The bio-solid application system has as its primary objective provision of adequate treatment of the WWTP sludge through the crop/soil system. A secondary goal is to maximize agricultural production. Operations are developed that remain consistent with these objectives. An essential element of land application is a manager that can direct and oversee day to day operations. This person will schedule applications that will coincide with the harvest schedule of the land owner, and track the applications. Site records will be kept at the wastewater treatment plant for the duration of the application and the 10 years beyond. Monitoring records will be kept of the sludge results, soil sample results and crop analyses as well as harvest records. Operational records that will be kept in the HACH WIMS computer program include: Dates of application Fields applied upon Volume of sludge applied Corresponding nitrogen and metal loadings Cumulative nitrogen (Excel) and metal loadings Annual dry tons applied per acre All sludge and soil lab analyses Lime applications in lbs./acre Results for all monitoring and application activities will be submitted in the Annual Sludge Report submitted to EPD by January 31 of each year to contain pollutant concentrations, required certification statements, pathogen and vector attraction reduction requirement documentations, annual bio-solids application rate, site locations, acreages, and quantity applied to each site. In addition, the Annual Sludge Report will be submitted to the EPA by February 19 of each year. The bio-solids will be slung via a tractor and pull behind ag-slinger soon after each hay crop is harvested. The 30 day waiting period before the next harvest will be honored by the land owner. The schedule for application will be decided through communication between the landowner and land application manager. Sludge will not be applied during periods of rain. The privately owned Little Dixie Landfill operated by BFI will be used at that time by dewatering the bio-solids and disposing of them in the landfill. The soil will be sampled at least annually and more as necessary to bring the soil pH to the desired level. PSRP PSRP will be met by following Alternative 1 in the schedule 40 CFR 503 regulations. This will be 6 fecal coliform samples using the geometric mean less than 2 million CFU per gram of bio-solids on a dry weight basis. A-5 Vector Attraction Reduction VSR will be met by following Option 10 in the schedule 40 CFR 503 regulations by the following method. Bio-solids will be incorporated into the soil within 6 hours of application to or placement on the land. Incorporation will be accomplished by plowing or some other means of mixing the bio-solids into the soil. Bio-solids Application Bio-solids will be loaded at the sludge loading station as a dewatered material at approximately 20% into the semi-dump trailer. The bio-solids will then be transported to the site where it will be surface spread and slung via a tractor and pull behind ag-slinger. The primary choice of bio-solid land application will be conducted utilizing a tractor and agslinger. The first step in this process will be to de-water the bio-solids from an estimated 2% solids from the solids holding tank to an estimated 20% solids utilizing belt filter presses and centrifuge located at the wastewater facility. The bio-solids will be loaded into a semi truck and trailer utilizing a front end loader and conveyor belt system extending from the belt filter presses. When the trailer has been filled with de-watered sludge, estimated to be between 18 and 20 tons, the trailer will be hauled to the pre-determined application site for that particular day. We will then dump the sludge on the designated dump site. A frond end loader will pick up the sludge from the dump site and empty its bucket into the ag-slinger. The tractor will then proceed into the field and after reaching the field start site, the tractor operator will engage the ag-slinger as to begin spreading the sludge in the crop row direction. The ag-slinger will spread the sludge on both sides of the machine approximately 60 feet outward. After the crop has been completely land applied to, or the daily allotted volume of sludge has been utilized and the only remnants of product to remain in the dump site is small pieces and insignificant volumes to begin another spread cycle, the dump area will be thoroughly cleaned by the front end loader and utilization of hand tools such as rakes and shovels if necessary. The tractor, ag-spreader, and dump site will be cleaned on a daily basis. At no time will equipment show visible signs of sludge or recent activities of spreading. When it becomes necessary to move the equipment from one application site to another, not only will the before mentioned equipment be thoroughly cleaned, but all transport equipment will be inspected and cleaned as well. During periods of adverse weather conditions, or times that would not be advantageous to the land owners for land application, all bio-solids will be de-watered as previously explained and the sludge will be transported and disposed of in the Little Dixie Landfill. All sludge disposed of via land application will be tracked and monitored for quality pertaining to the applicable current state and federal regulations as well as land applied volume measured in tonnage. As well, all sludge disposed of via land fill will be tracked and monitored for quality pertaining to the applicable current state and federal regulations as well as land filled volume measured in tonnage. A-6 Sludge Monitoring Plan Nutrients and Metals The nutrient and metals analyses will be performed on an every other month basis in accordance with the annual dry tons. Representative samples will be collected to demonstrate compliance. Vector Attraction Reduction VSR will be met by following Option 10 in the schedule 40 CFR 503 regulations by the following method. Bio-solids will be incorporated into the soil within 6 hours of application to or placement on the land. Incorporation will be accomplished by plowing or some other means of mixing the bio-solids into the soil. Pathogen Reduction PSRP will be met by following Alternative 1 in the schedule 40 CFR 503 regulations. This will be 6 fecal coliform samples using the geometric mean less than 2 million CFU per gram of bio-solids on a dry weight basis. Enough samples will be analyzed to truly represent pathogen reduction. A-7 Appendix B Wastewater Treatment Plant Standard Operating Procedures 1. 2. 3. 4. 5.

However, equipment failures, collection system Inflow and Infiltration (I&I) or extreme operating conditions may limit the ability to process all flows coming to the treatment plant. These guidelines and instructions support minimizing the occurrence of treatment works bypass events and mitigating impacts should bypass be unavoidable. A discussion of the causes and guidelines for reducing overflows of raw sewage are presented in the Standard Operating Procedure (SOP). A bypass of any part of the treatment system is a significant incident and should be managed in accordance with United Water (UW) policy. A bypass may be elevated to major incident designation if the discharge occurs during dry weather or is of a magnitude great enough to cause upstream manhole surcharge and is also in direct violation of the existing EPA Consent Decree. Specific notification responsibilities will be addressed in a later section. DISCLAIMER: This document was prepared in expectation of the storm cell lagoons being completely empty of water and free of excess solids content, as well as, all referenced raw influent pumps, and all other plant process equipment and basins, being in proper operating condition and available for utilization. At the time of this document inception, May 2014, the referenced storm cells have been dredged and cleaned to a yet to be determined level, and only two 30 mgd raw influent pumps are operational and available for use. PROCESS OBJECTIVE In keeping with BEST practices, and to lessen potential adverse effects to the environment and human health, the preference is to treat combined flows during wet weather events to at least some degree of treatment. Ideally, full treatment up to the wastewater plants permitted capacity should be accomplished prior to diverting and storing water in the storm cells and bypass channel. This allows for, at a minimum, dis-infection of bypassed water compared with no treatment when overflows are experienced in the collection system. 1 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Pump all influent flows entering the facility to proper treatment according to the normal sequence of unit processes Gradual increases in flow to avoid solids washout from the sedimentation basins Maximize treatment to all flows entering the facility Closely monitor, control and limit flows bypassed around treatment units or overflow due to facility capacity limits Avoid damage to upstream private and public property Avoid facility damage Limit possible environmental and health impacts from bypass events Investigate and evaluate all bypass incidents to ascertain causes and to identify improvements that will help reduce the frequency and duration of future recurrences PROCESS PERFORMANCE GOALS Protect treatment plant from flooding which would impair long term operations Reducing flow bottle necks Limit solids washout from the secondary clarifiers which would impair treatment plant long term operations Temporarily alter operational conditions to maximize flow through available equipment Maintain positive control of the influent pumping process Maximize combined storm water treatment during wet weather events by: 1. Capturing the maximum amount of combined storm flow in the storm cell lagoons 2. Bypassing combined storm flow when lagoons are full and collection system flows remain high 3. Providing disinfection to bypasses combined storm flow (This alternative is a better practice than allowing untreated discharges from manholes and lift stations in the collection system) 4. Recovering stored storm water flow to the treatment plant as plant capacity limits allow and emptying the stored combined water as soon as practical from the storm cell lagoons and bypass channel 5. Maintain all storm cell lagoons at an empty level to provide maximum available capacity for the next wet weather event 2 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 PROCESS PERFORMANCE INDICATORS Plants (raw sewage) bypass condition Flooding of plant areas Associated equipment shutdown or failure to start when needed Sewer system surcharge PLANT BYPASS LOCATIONS The Savanna Street wastewater treatment facility has the ability to divert wet weather flows into storm holding ponds. When those ponds reach their capacity, excess flow is then disinfected and discharged with the plant effluent into the receiving stream (Pearl River). A manual bar screen allows for flows exceeding the hydraulic capacity of the Headwork’s Bar Screens to be diverted A bypass exists to allow flow to be diverted around the grit removal system A bypass exists around the current UV disinfection system. That bypass is currently used at all times and effluent disinfection is by chlorine TREATMENT LEVEL PRIORITY All flows entering the facility should receive treatment according to the normal sequence of unit processes. Equipment failures or extreme operational conditions, however, may limit the ability to handle all flows. Should it become necessary to bypass portions of the treatment facilities, there exists a definite order of preference for point of discharge in the treatment process where flows should be discharged. Treatment level priorities are presented as follows in descending order of preference with the most preferred at the top of the list and the least preferred at the bottom of the list. 3 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Diversion of flow through the manual bar screen when the level of the headwork’s structure approaches overflow Bypass of the Grit System when headwork’s levels approach overflow Diversion of influent raw sewage into the storm lagoons when flows exceed one of the following criteria: o Calculated Solids Flux analysis maximum treatable flow is exceeded o Influent structure is near overflow o All available pumping equipment is online Influent is diverted first by opening the West Rankin Gate #2 and Closing West Ranking Gate #1 Additional Influent flow is diverted to the storm lagoon using the 100 MGD pump or by opening the 54 inch sluice gate between the 30 MGD pumps and the 100 MGD pump PROCEDURES FOR BYPASS AVOIDANCE/MINIMIZATION Under normal operating conditions, all flow will be accepted into the plant and processed routinely without problem. However, under conditions of high flows, wet weather events, failure of influent screens or limited pumping capacity, plant operators will implement procedural methods that will reduce the risk that a bypass will be necessary. Accordingly, an operational strategy for reducing the likelihood for a bypass involves the following: Reducing flow bottle necks Temporarily altering operational conditions to maximize flow through available equipment Making adjustments to plant flow conditions in gradual increments to lessen the impact on influent pump operation Preparation for wet weather operational conditions should be started early because flows can quickly increase with little time for reaction. This is particularly true during periods of intense rain or after periods of prolonged rain when the ground has become saturated and there is increased potential for inflow, infiltration and surface runoff into the collection system sewers. Flows can increase dramatically even at non-peak periods. Wet weather preparation should include the following: 4 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Anticipate quick need to place the screening equipment on Hand in the event of a rapid flow increase Placing Grit removal equipment on Hand When weather forecasts indicate a strong potential for rains, high flow conditions should be anticipated Defer if possible non-essential maintenance that would require disabling the standby equipment to an alternate time or schedule the work to be started and completed during the plant low flow period When inclement weather is forecast, ensure that all emergency generators are operational Increase frequency of operator rounds to check for obstructions and proper function of all process equipment The following table illustrates the operating status of most major equipment during normal (non-wet weather) flow periods: North Influent Gate #1 NORMAL OPERATING MODES Normally Open 100% North Influent Gate #2 Normally Closed.

The Wet Well levels must be closely monitored and additional raw sewage pumps placed on line to maintain the wet well level at safe operating depths if the wet well level indicators do not respond to rising wet wells. Additional pumps 7 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 should be placed on line as early as possible to prevent flow surging and washout of solids in the secondary clarifiers. A fast rising level will require fast response for additional pumping capacity to prevent overflows and flow surges through the process. During normal dry weather operating days the desired wetwell level is maintained at between 10 and 15 feet. When wet weather has been forecasted the wet well level is controlled at 10 feet. Prior to predicted rainfall, the polymer feed system located at the secondary clarifier splitter box is placed into service in order to inject polymer into the RAS system and assist in settling of solids and ultimately allow for additional flow to clarifiers. As the wet well level increases additional 30 MGD pumps are placed online until one of the following conditions are met: Calculated Solids Flux analysis maximum treatable flow is exceeded Headwork’s structure is near overflow All available pumping equipment is online 2. When one or more of the above criteria has been met and wet well levels continue to rise and reaches a level of 21feet: Discontinue any Storm Lagoon recovery pumps or flows from the diversion channel gates Open The West Rankin gate #2 and close West Rankin Gate #1 to allow diversion of the West Rankin flow to the storm water lagoons 3. If wet well levels continue to rise and flow to the treatment plant has not been maximized: Continue placing 30 MGD pumps online until all three are online at 100% pumping speed Discontinue Dewatering process and sludge wasting to minimize in-plant recycle flows and their impact on the diversion flow. NOTE: Verify with the Operations Manager before discontinuing Dewater and Waste Flows Discontinue accepting water from leachate and septic tank haulers into the treatment plant Discontinue leachate pumping from the storm cell bag storage areas Begin Opening the 54 inch gate to allow diversion of some of the influent flow to the storm lagoon while still maintaining maximum flow to the treatment plant as defined by the criteria above 8 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 4. If all available 30 MGD pumps are in service at 100% speed and the flow to the treatment plant has been maximized and the wet well level continues to rise above 23 feet, close the 54 inch gate and use the 100 MGD pump at minimum speed to allow diversion of flow into the storm lagoons and control the wet well level below 23 feet 5. Once all available pumping equipment is online with maximum flow to the treatment plant and all available diversion flow to the storm lagoons, restrict the north gate #1 to 5% to allow for storage in the collections system and to keep the influent wet well below 23 feet. If the wetwell continues to rise, the north gate #1 should be further restricted in 1% increments until the gate is 100% completely shut. NOTE: Shutting the north gate #1 completely is the final and last option. However, wetwell levels above 25 feet create a dire circumstance due to danger of flooding the dry pit and catastrophic failure of motors and controls and should be avoided at all costs. Location Influent Pumping Station Task 1. Monitor wet well levels and flows 9 of 15 Steps a. Monitor wet well level and try to maintain control at 10 feet during wet weather. b. Add additional pumps as required to maintain the wet well level until one or more of the following criteria are met: o Calculated Solids Flux analysis maximum treatable flow is exceeded o Influent structure is near overflow o All available pumping Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Location Headwork’s Task 2. When flows near or exceeds 60 MGD notify Operations Manager and place influent screens and Grit removal systems in Hand operation Steps equipment is online. a. Place the Auto/Hand Switches to Hand 6. Secondary Clarifiers The Secondary Clarifiers ability to process high wet weather flows is largely dependent on the aeration systems ability to produce a sludge that readily separates and settles rapidly. A model (Solids Flux Analysis) for the Secondary Clarifiers at the Jackson Mississippi Savanna Street Wastewater Treatment Facility has been developed in order to predict the flow at which the Secondary Clarifiers will begin to become overloaded and allow washout solids to be carried through the effluent. Prior to any storm event, check the Daily Exception Report’s Solids Flux analysis sheet for an indication as to how much flow the Secondary Clarifiers will be able to properly accommodate. 7. Chlorination / De-Chlorination Place Chlorination / De-chlorination equipment online for the diversion flow once the storm lagoons reach full capacity and flow begins to exit the storm lagoons and enter the diversion channel. Notify the Lab Supervisor that a diversion is taking place and follow instructions for collecting the required additional NPDES samples. 10 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Consult any recent Process Control Orders and/or Operating orders for Total and Free Chlorine Residual control set points. 8. Post Bypass Event After the bypass event has ceased to exist, the following steps should be initiated: Chemical feeds to the bypass channel should be discontinued The plant valve work pertaining to process control should be returned to normal operating status in reverse order of the aforementioned steps The North Gate #1 re-opened to 100% The screenings and grit systems should be returned to “auto” control Finally, when wetwell levels are back within normal operating range, diverted water remaining in the bypass channel and storm lagoons should immediately be recovered to the facility for proper treatment. This task can be performed by either utilizing a mechanical recovery pump or by engaging the electronic gate valves located in the bypass channel invert and allowing for gravity return to the influent wetwell Resume De-watering process and sludge wasting recycle flows Resume accepting water from leachate and septic haulers and vendors Resume leachate pumping from storm cell bag storage areas Bypass Preparedness Plant operations and maintenance personnel must be immediately available, continuously aware of plant operational conditions, and ready to implement response actions which have been thought out, planned for and practiced in advance. Should a situation arise where plant bypassing is unavoidable, close control over plant flows and pumping will be necessary to minimize the volume of water diverted. Always visually verify an alarm indicating a high level condition. Finally, system monitoring instrumentation must be on a program of routine regular calibration to assure the validity of indicated values and to enhance personnel confidence. 11 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 A. O&M Tech Presence: Plant process equipment is equipped with sensors that monitor critical process conditions. These sensors are set to trigger various alarms to alert plant personnel of adverse conditions so that corrective actions can be taken. It is still necessary, however, that plant personnel perform routine inspections of support equipment and systems as a verifying check on correct performance of field instruments. In addition, routine observation by plant personnel helps to identify deteriorating trends in performance so that corrective actions can be implemented prior to the development of an alarm condition that could require immediate and dramatic action to resolve. B. Preparedness Documentation: C. Maintain continuous personnel presence in the pumping area or at the SCADA monitor screen to provide for immediate emergency response. Close monitoring of the return rate and clarifier performance will provide indications of process integrity as secondary flows increase. Operating conditions are observed every two hours and recorded on the plant log The O&M Tech will inspect the plant systems and record status in the plant log book Report equipment deficiencies to the Maintenance Supervisor and/or Maintenance Manager and note in the log book. Have work requests immediately entered for items requiring other than minor maintenance Routine Instrument Calibration: Critical instrumentation must be checked regularly and placed on a formal calibration program. This is to assure accurate representation of field conditions which cannot be easily or directly observed by plant personnel (currently calibrated at a minimum of annually) 12 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Notification Responsibilities According to NPDES permit requirements, verbal notification to MSDEQ must be made within 24 hours of events in which flows are bypassed around treatment processes. Also, during the Consent Decree period, the Consent Decree manager should be immediately notified of the condition. In addition, follow up written notification to the MSDEQ within 5 days is also required. Further, notifications are also required to provide for clear internal communication with UW and The City of Jackson MS. The plant Shift Operator is responsible for initiating preliminary verbal notifications and making follow up calls to confirm and revise information as outlined in the UW guidelines. A. Wet Weather Incident Report: During high flow events, the O&M Tech will make additional notes as to hourly flows, rainfall amounts and action items taken during a high flow event. Additionally, items that would require this guideline to be modified in order to improve the plants ability to process high flows should be noted B. Contact Lists: Immediate contact of the Plant Operations Manager as indicated in this UW Notification Policy whenever it becomes apparent that a Wet Weather incident that may cause an increase in plant flows above 60 MGD. Please see the emergency contact list for contact numbers. The following list is provided for reference: C. Project Manager / Operations Manager – when flows reach 60 MGD Operations Supervisor so that the UW 800 line and MSDEQ contacts can be made Bypass Incident Investigation and Report (Intelex) 13 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Each time a plant high flow or bypass event occurs a complete investigation shall be conducted and a written report prepared. The Shift O&M Tech Lead and Plant Operations Supervisor will conduct an initial investigation and prepare the preliminary report. For Wet Weather Reports, a report should be filed whenever there is a high flow event where a diversion into the storm lagoons has occurred and resulted in a treatment bypass The Plant Operations Supervisor will conduct a final investigation if necessary for further refinement. The initial report shall be submitted to the Project Manager within 24 hours of an occurrence. It is essential that the Shift O&M Tech Lead and Operations Supervisor conduct a timely initial investigation of the events leading to and surrounding high flow or bypass events. The investigation is conducted to determine exactly what happened and what actions can be taken in the future to prevent or minimize the impact of future wet weather flows. The investigation therefore provides the basis for a learning opportunity to improve the performance of plant facilities and effectiveness of staff teamwork. Essentials of the investigation are as follows: Obtain statements from all O&M Techs on duty and/or from operator log book notes Statements to include descriptions of significant events and their sequence Conduct a debriefing, with involved staff to clarify events and resolve any discrepancies Information determined during the course of the investigation is to be reported in a formal report. The report provides the Project Manager and Operations Manager with vital information for assessing equipment reliability and priority of support by maintenance, training and engineering groups. The report is to include the following: Summary Description of the event Significance with respect to NPDES permit compliance 14 of 15 Jackson MS Savanna Street Wastewater Treatment Facility Treatment Works Bypass Minimization and Wet Weather Operating Plan Standard Operating Procedures May 2014 Statement of findings Conclusions as to what happened and why Identification of extenuating or contributing factors Recommendations of how to prevent future occurrences Copies of all supporting charts, records and logs Listing of personnel on duty and assigned posts Ultimately, was the event non-avoidable Operating records, logs and the SCADA monitor system provide an important source of information when conducting investigations to identify causes of operational and mechanical problems. Accordingly, to provide more complete data and records on plant high flow, overflow events, or bypass events, a complete investigation should be conducted and report filed as a standard procedure whenever there is such an event. The investigation would include compilation of all relevant documentation and interviews with involved parties, preferable immediately following the incident. Important documents consist of log book entries, data logs, charts for plant flows and levels, and written statements. The formal report should contain an incident description identifying occurrences, conditions and sequence of events; identification of actual or probable causes and contributing circumstances; statements of findings; conclusions; recommendations of how to prevent recurrence and specific mitigating actions with responsible parties identified. 15 of 15 WWTP POWER FAILURE SOP STANDARD OPERATING PROCEDURE JACKSON, MS - SAVANNA STREET WWTP Original Release Date: _8-23-11______________ Revision Date: _3/9/2012_ Authorization: _Darnell Gray_/ Eddy Russell_____ Reference Document(s): _N/A_____________________ Purpose: For personnel to be familiar with procedures taken in case of temporary power loss at lift station facilities.
